Suction hose for water pump

The working pressures listed for this series are 2.5 – 5 bar. Use the value for the selected model and grade, not the highest value across the series. Working pressure and burst pressure are separate limits; a burst-test value is not an operating pressure. Where BP is listed, use its pairing with WP in the same row; do not assume one burst ratio for every model. The model table does not document a vacuum limit. Request a suction rating for the exact size, temperature and duty before selection; positive-pressure values do not establish full-vacuum capability. The listed model and material define the standard specification shown here. Treat requests for other compounds, colors, reinforcement, sizes or compliance documents as separate options, subject to written confirmation. A generic material name or standard reference is not a certificate for every model.
